Default settings after start-

Once the switch has started successfully, installation is complete and

up

the switch is using its default setting (also known as default configu-

 

ration):

 

• All ports are enabled.

 

• All ports operate in auto-negotiation mode.

 

• Spanning Tree is disabled on all ports.

 

• Addresses that have been silent for more than 15 minutes are

 

purged from the switch’s address table (the MAC Address Aging

 

time).

 

• No access restrictions to Local Management (Telnet).

 

• No SNMP restrictions.

 

• No permanent MAC address entries defined. A permanent entry

 

is a MAC address that is defined as being permitted only on a

 

certain port. This can be a useful security feature.

 

• All ports are in the same VLAN (named <System>) and VLAN

 

mode (Stand-alone mode). VLANs allow you to create virtual

 

networks using specific switch ports, IP addresses, IP subnets

 

and MAC addresses.

 

• Flow Control is enabled on all ports.

 

• The connection with Local Management is timed-out after 10

 

minutes if there has been no input during this period.

After start-up

This default configuration is adequate for simple workgroup environ-

 

ments to operate in basic switching mode.

 

Although the switch continues to operate without problems, we rec-

 

ommend that you change certain parameters to suit your own require-

 

ments.

520T specifications

The Intel 520T is a well-regarded member of Intel's Xeon processor family, designed primarily for entry-level servers and workstations. Built on the 32nm manufacturing process, the 520T is based on the Nehalem microarchitecture, which has paved the way for improved performance and efficiency in data processing tasks.

One of the standout features of the Intel 520T is its energy efficiency. With a thermal design power (TDP) of just 35 watts, it provides an excellent balance between performance and power consumption. This characteristic makes it particularly suitable for environments where energy costs are a significant concern, such as in data centers or small business server applications.

Equipped with four physical cores and hyper-threading technology, the 520T allows for eight threads of execution, enabling it to handle multi-threaded workloads effectively. It operates at a base clock speed of 2.2 GHz and can achieve turbo boost frequencies up to 2.5 GHz under optimal conditions, ensuring that it provides the necessary performance for demanding applications.

The processor supports Intel's trusted execution technology and virtualization technology, maximizing both security and performance in virtualized environments. This capability allows multiple operating systems to run simultaneously on a physical server, making it an excellent fit for businesses looking to optimize their assets through virtualization.

The Intel 520T also features Intel's QuickPath Interconnect (QPI) technology, which provides a high-speed connection between the processor and other components, such as memory and storage. This feature helps minimize latency and maximizes bandwidth, enhancing overall system responsiveness.

In terms of memory support, the processor can handle up to 32 GB of DDR3 RAM, providing ample capacity for demanding applications. The 520T also supports ECC (Error-Correcting Code) memory, which is vital for mission-critical applications that require data integrity.

Security enhancements are another noteworthy aspect of the Intel 520T. With built-in security technologies, including hardware-based random number generation, the processor helps safeguard sensitive data and contributes to more secure computing environments.

Overall, the Intel 520T stands out as a robust option for users seeking an efficient server-grade processor capable of delivering strong performance while maintaining a low power profile. Its array of features, technologies, and characteristics make it a reliable choice for various computing needs.
